Application filed February 17, 1908. Serial No. 416,281.

To all whom 'it may concern. l

Be it known that we, MAX STOERR and l MAX` KUETTNER, both subjects ofthe Emi peror of Germany, and both residing at Oornfort, in the countyof Kendall and State of l Texas, have invented certain new and useful lImprovements in Rotary Brushes, of which l the following is aspecification.

This invention comprises a novel form of brush of the rotary type, andin accordance with the invention it is proposed to provide a desirabledevice of this class, operable by a suitable motor7 and in which thevarious parts are assembled in an advantageous many ner, designed tosecure compactness of strucl ture and to economize space.

Other objects of the invention are to employ special mechanismpermitting of ready substitution of another brush for that upon thedevice, to be used for some different purposes, and to embody in theconstruction of the invention peculiar means for controlling theoperation of the brush by the motor.

Other objects and advantages of the presi ent invention will be notedupon reference to l the following detail description, and to theaccompanying' drawings, in which:

Figure 1 is a plan view of a brush constructed in accordance with ourinvention 1 Fig. 2 is a horizontal sectional view; Fig. 3 is a verticalsection taken about on the line Fig. 4 is a detail section of theratchet means cooperating with the spring motor; and Fig. 5 is an endelevation showmodiiied adaptation of the invention.

Similar' reference characters refer to similar parts throughout thedescription and drawings. y

Specifically describing the invention,'and referring to the drawings,the numeral 1 designates a circular brush which is mounted for rotationupon a head 2 with which is preferably connected a handle 3 The han- 4,this being desirable in order that handles of different lengths may beused in connection with the brush, dependent upon the particular use forwhich the device is to be employed. The brush 1 is mounted upon the head2 in a peculiar manner. The head 2 comprises a tubular orhollow bodyadapted to receive at its ends spindles 5 of end members or sectionswhich are directly connected with the body of the brush.

The end members are indicated 6 and 7,

the member 6 being formed with an integr-al socket 8 which is adapted tobe received easily in a recess 9 provided in one end of the body of thebrush 1. In like manner, the end member 7 is connected with a small Ushaped frame 10, secured thereto by the threaded connection 11, saidframe being received in a recess 12 formed in the end of the brush bodyopposite that having the recess 9. The outer end of the recess 12 isclosed by a plate 13 secured by fastening means to the frame 10.

Broadly speaking the head 2 carries end sections or members 6 and 7, andthe latter carry supporting members, 8 and 10, which are connected atopposite ends of the brush body in such a way as to permit readyrotation of the brush when operated in a manner to be described. Thesupporting member or socket 8 receives a spring motor consisting of adrum or casing 14 in which is arranged a spring 15 connected with ashaft 16. The shaft 16 is a two-part shaft composed of the part 16asecured to the spring motor, and the part 16b secured to the frame 10,which frame supports governor mechanism coacting with the motor. Theinner ends of the two parts of the shaft 16 are received in an openingthrough the body of the brush 1 and the meeting extremities of saidparts interlock at 17 to establish a driving connection therebetween.The opening in the brush body which receives the end of the shaftelements is preferably of oblong formation to conform to a similarformation of the shaft, and the brush is thus connected with the shaftin such a manner as to rotate therewith. A ratchet wheel 18 is appliedto the casing 14 and a pawl 19 coacts therewith to prevent unwinding ofthe spring 15 except when the shaft connected therewith rotates. Thespring motor is wound up in an obvious way by turning of the handle 2()attached to the casing 14.

To the outer end of shaft part 16b is attached a gear 21 in mesh withpinion 22 mounted on a governor shaft 23. A small fan governor 24 iscarried by the shaft 23 and is of course operated by the motor when thebrush 1 is rotated. A sliding pin 25 mounted on the frame 10 and plate13 constituted means arranged to engage the member 24 in order tocontrol the operation of the motor, so that the latter may be stopped orstarted at will.

A suitable cleaning comb is provided for the brush and is indicated at26. The device 26 embodies teeth arranged to engage the fibers of thebrushto accomplish the desired result. Fastening members 27 are employedto secure the cleaner 26 and body of the head 2 to the end members 6 and7. Said members 27 consisting of thumb screws passing through thetubular body of the head 2 and engaging the spindles 5 of the members 6and 7 so as to detachably secure the said members in position.

It is contemplated to use different brushes in connection with thesupporting and operating mechanism above described and hence it isnecessary and desirable that a brush may be quickly removed from, orattached to the supporting means. One brush may be used for cleaningcarpets, another for the purpose of the bath, another for cleaningshoes, and others for different purposes, as will be readilyappreciated. To remove the brush l it is only necessary to unscrew thefastenings 27 and separate the end members 6 and 7 by outward movementthereof until the shaft parts, and supporting devices 10 and 8 aredisengaged froml the body of the brush. A different brush may then bequickly substituted for that removed and the arts 6 and 7 with memberscarried thereby fbrced together until properly positioned with res ectto one another so as to support the brus in/a manner in which it may Abereadily operated.

Should it be desired to use the brush for bath purposes mainly, theinvention may be supported by a wall, or other support, in the mannershown in Fig. 5 of the drawings, in which instance, the body of the head2 is engaged with the upper portion of a bracket plate 28 directlysecured to the support. The operation of the brush when supported as inFig. 5 may be readily controlled in an evident manner.

Having thus described the invention, what is claimed as new, is:

l. ln a rotary brush, the combination of a `head embod ing separablesupporting members, a brus motor mechanism carried by one of thesupporting members aforesaid and governor mechanism carried by the otherof said supporting members, and a shaft connected with the brush andcomprising parts separable with the supporting members, one art of theshaft being connected to and movable with the motor mechanism while theother part of the shaft is similarly connected with the governormechanism.

2. In means of the class described, the combination of a brush providedat opposite ends with recesses, a two-part shaft upon which the brush ismounted, motor mechanism in one of the recesses of the brush andconnected with one of the parts of the shaft, governor mechanism in theother recess of the brush and connected with the other shaft art, theshaft parts being separable and connected by a driving connection, ahead comprising separable end members one of which has connection withthe governor mechanism and the other of which is connected with themotor mechanism, and means connecting the end members aforesaid andholding the motor and governor mechanisms in operative relation to thebrush.

3. ln a device of the class described, the combination of a headcomprising separable members, a shaft mounted upon said members andcomprising parts having a driving connection with each other, one partof the shaft being mounted on one member of the head while the other iscarried by the other member of the head, motor mechanism operablyconnected with the shaft, and means connecting the separable members ofthe head together and normally operatively connecting the parts of thedrive shaft.

4. ln a device of the class described, the combination of a circularbrush the body of which is provided with recesses in its opposite ends,a supporting head comprising a tubular body and separable end members,spindles projecting from the end members and received in the tubularbody of the head, fastenings securing the body and end members of thehead together, a spring motor comprising a casing received in one of therecesses of the brush body and a spring in said casing, means connectingthe motor mechanism and one end 'member of the head, governor mechanismconnected with the other end memberof the head and comprising a framearranged in the recess of the brush opposite that receiving the motorcasing, a two-part shaft passing through the body of the brush andconnected for rotation of the latter, a driving connection between theparts of said shaft, one of the shaft parts being connected with thespring motor for operation thereby, the other of said shaft parts beingmounted on the frame of the governor mechanism, a governor fan mountedon said frame and operable by the shaft aforesaid, and a membercontrolling the movement of the fan to stop and start the motor.
